The invention relates to improvements in rigid and flexible pipe and conduit couplings and has particular and .specific reference to means for hermetically sealing rigid and flexible pipe ends or taps into adjacent structnree such as cylinders, chambers, vacuum and other similar members.

The object of the invention resides in the providing of a supporting coupling member 1' provided with an ensealing seat arranged to receive the end of a ipe connection carrying a soft or semi-pliab e metallic sleeve engagingsaid ensea seat, together with a stufiin box member or am-nut detachably mounte in said coupling member and in contact with said semi-tractable sleeve adapted to draw the same into contact with said seat to cause a slight distortion in the body of said sleeve at its point of contact to form a hermetically e means for divers formsof pipe and forms 0 conduit means.

Another object of the invention consists of a plying semi-tractable sleeves to both and flexible tubing or piping for use in :5 connection with all known forms of couplings to insure leak-proof connective means for structures employing liquid or air carrying conduits.

In the following there is described a general an embodiment of t e invention, the particular and broad features thereof being pointed out hereinafter in the claim.

In the drawings Fig. 1 is an elevation partly in longitudinal section of the coupling as applied to a form of resilient pipe or conduit and showing the same as connected directly with an adjoining body such as a chamber or the like; and Fig. 2 is an elevation partly in section of a flexible pipe section having attached to its respective ends thereof a pair of semi-tractable metallic sleeves for use 1n connection with varied form of conduit couplings.

Similar numerals of reference indicate similar parts throughout the several views.

In the drawings 1 designates the wall section of a chamber or other enclosed structure of a like nature and is provided with a threaded aperture 2 arran ed to receive the threaded nipple end 3 o supporting coupling member 4. Said member 4 ma be made in any suitable form and size and 0 any metal and has formed therein a chamber 6 communicating with a passage-way or bore 6 and has formed at the intersection of said chamber 4 and bore 6 a seat 7. Seat 7 is formed by millin an annular rim 8 into a sharp ridge 9 of afiesser diameter than chamber 5 of a greater diameter than bore 6, and the peripheral surface of ridge 9 receives the end of semi-tractable metallic sleeve 10 rigidly attached to pipe connection 11, the outer end thereof being tapered at 12 to receive jam-nut or stufiing head 13, the latter element thereof being externally threaded at 14 to engage the threaded bore 15 of chamber 5 and havmg formed therewith a hexagonal head 16 for locking urposes.

By reason of the act that seat 7 is of hardened metallic body, and sleeve 10 of a semipliant or tractable metal the forced pressure of jam-nut 13, the end of said sleeve 10 distorts to a slight extent and forms at the juncture point 0 the engagin members thereof a positive hermetic ensea ing means. H

In Fig. 2 of the drawings the structure therein shows a flexible pipe connection 17 having fastened on its respective end attaching semi-pliant metallic sleeves 18 for combined use in connection with the herein de scribed type of pipe coupling or in fact for use in combination with any other form of coupling.

It is obvious that the structure ma be altered in many ways without departing m the general scope of the invention.

What is claimed and desired to secure by Letters Patent of.the United States is:

a device of the character described including a coupling head for metallic pipe or duct ends com rising-a recessed body internally threaded in a portion of its area and chambered in the remaining portion, and having formed at the bottom thereof a rimmed seat, a hose end connection mounted in said recessed body, a tractable metallic sleeve of a lesser diameter than the diameter of said chambered recess mounted in said chamber and engaging said seat and the surface of said hose end, and a pack-nut mounted in the 100 Z mamas threaded portion of said recess adapted to en ge said tractable sleeve and when tightened to the limit of its movement in 881d body partly distort said sleeve to seal the same on 5 said seat and around all of the surface of said hose end within said body, and by reason of the difierence in the diameters of said recessed chamber and sleeve provide means for formin% new seats during the adjustment of the re ative parts thereo In testimony whereof I have signed my name to this specification this 24th day oi January, 1927.
